3 QUESTIONS - What is a stenosis, what happens to the blood flow as it encounters to stenosis, and what change occurs in the blood pressure with in the stenosis?

3 QUESTIONS - According to Bernoulli's Principle, what happens to velocity and pressure within a stenosis, what type of energy is primarily responsible for the movement of blood through a vessel, why is the conservation of energy important in understanding blood flow through a stenosis?

3 QUESTTIONS - Which Doppler finding indicates blood flowing through a stenosis, which finding is typically seen distal to a stenosis, why does the velocity increase in a stenotic area?

3 QUESTIONS - What are the main factor that determine hydrostatic pressure in the circulatory system, why is the blood pressure cuff placed at the level of the heart when taking a blood pressure, why is hydrostatic pressure negative above the heart?

3 QUESTIONS - Which layer of the vessel wall is responsible for allowing arteries to handle higher pressures, which vessels contain valves to prevent backflow of blood, what is the primary function of capillaries in the circulatory system?

3 QUESTIONS - Which muscle is primarily responsible for the changes in pressure between the thoracic and abdominal cavities during respiration, what effect does inhalation have on venous flow from the legs, what role do the valves play in venous return?
